Improved rudder



*NTTEE' STATES PETER DINZEY, OF ST. BARTHOLOMEW, WEST INDIES.

llVlPROVED RUDDER.

Specification forming part of Letters Patent No. 55,028, dated May 22, 1866.

vTo all whom fit may concern:

Be it known that I, PETER DINZEY, of St. Bartholomew, West Indies, have invented an Improvement in Itudders of Vessels; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention consists of certain mechanism (fully described l1ereafter,) to be used in connection with rndders for the purpose of rendering the same more capable of withstanding the strains to which they are subjected than ordinary rudders, and for the further purpose of enabling the hclmsman to perform his duties with less exertion.

In order to enable others skilled in the art to make and apply my invention, I will now proceed to describe the manner of carrying it into effect.

0n reference to the aecompanyin g drawing which forms a part of this specieation, Figure l is a sectional elevation, showing the stern of a vessel with my improved rudder at# tached; Fig. 2 a plan view, and Fig. 3 an inverted plan view.

A is the stern-post of a vessel, to which the rudder B is hung by the usual pintle 7a, the post a of the rudder extending above the deck of the vessel, where it is furnished with a tiller, b.

In the rudder. turns the diagonal shaft C, which extends through a curved slotin the overhang x of the vessel, and through the tiller b, and to the upper end ofthe shaft is secured a grooved pulley, o. The lower end of the shaft C projects from the rudder near the outer lower corner of the same, and is formed into a pin-A ion, o, the teeth of which gear into those of a segment, D, secured to and projecting from the heel of the rudder-post.

In suitable standards secured to the deck of the vessel turns a shaft, E, on which is the usual steering-wheel fand a grooved pulley,

g, and round the latter, aswell as round guidepnlleys m m', turning in snatch-blocks secured to the bnlwarks or deck of the vessel, and round the pulley c, passes an endless rope or chain, t'.

At the outer end of the tiller b are eyes n fn, for a purpose described hereafter.

The shaft E is turned by means of the steering-wheelf, and the rope or chain t' is caused to turn the pulley c, and with it the shaft C, the pinion @traversing the toothed edge of the segment D, so that the rudder must turn on its pintle h in a direction depending upon that in which the steering-wheel is turned.

By the mechanism described the rudder is not only easily operated, butitis held steadily in any position to which it may be turned, at the expense of much less labor on the part of the helmsman than an ordinary rudder.

As the rudder is always supported at its outer lower end by the shaft C and segment D, it is capable of withstanding greater strains than a rudder depending solely for its support on the pintle by which it is hung to the stern-post.

The gearing is simple and not liable to get out of order. Should it become injured in any way, however, the shaft C may be entirely withdrawn, and the rope i, after being detached from the pulley o, can be secured to the eyes fn, on the arm b, when the rudder may be operated in the ordinary manner.

I claim as my invention and desire to secure by Letters Patent- The rudder B, with its shaft ,(l and pinion e, in combination with the segment D, the whole being arranged and operating substantially as and for the purpose specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

PETER DINZEY.
